When controlling blood sugar, a diet rich in healthy carbohydrates, fiber-rich foods, heart-healthy fish and fats containing monounsaturated and polyunsaturated is recommended, according to the Mayo Clinic. Patients at risk for high blood sugar should avoid over-consumption of sodium, cholesterol and trans and saturated fats.
Although individuals attempting to control blood sugar should avoid over-consumption of carbohydrates, healthy carbohydrates such as vegetables, whole grains, low-fat dairy products and fruits are recommended, according to the Mayo Clinic. Fiber-rich foods also help control blood sugar levels. Foods rich in fiber include whole-wheat flour, wheat bran, nuts, beans, vegetable and fruits.
Fish is typically the preferred alternative to high-fat meats when people are working to control blood sugar, according to the Mayo Clinic. Tuna, cod and halibut are healthy additions to the diet because they contain less saturated fat than poultry and meat. Heart-healthy fish such as salmon, tuna, sardines and bluefish are also rich in omega-3 fatty acids.
Diabetes patients should also opt for good fats such as olive oil, peanut oil, walnuts, pecans, avocados and almonds to lower cholesterol levels and control blood sugar, suggests the Mayo Clinic. Good fats should be eaten in moderation, however, because they are often high in calories.
